Excessive Use of Chemical Fertilizers Make the Soil

IN PLANTING WE MUST USE THE RIGHT AMOUNT OF FERTILIZER NOT TOO MUCH AND NOT. Agricultural practices and the excess use of chemical fertilizers in the soil contribute to the accumulation of nutrients.

The Importance Of Using Chemical Fertilizers Fgs

Answer 1 of 4.

. However a recent study finds that excessive P-fertilizer may actually hurt the plants it is trying to help by altering the composition and function of. The over use of Chemical fertilizer has resulted to Hardened soil Decreased in Fertility low soil quality increased used of Pesticide and Herbicide Polluted air. Although chemical fertilizer has been a blessing to humanity in the past today Chemical Fertilizer has been determined to be the second cause of Soil Degradation after soil erosion Tetteh 2015.

Although nitrogen fertilizer contributes substantially to yield enhancement but excessive use of this manure has posed serious threats to environment and human health. Excessive use of chemical fertilizers is a very serious problem in agriculture at presentExcessive use of chemical fertilizer not only leads to soil compaction aggravating acidification and cause the fertilizer utilization rate is extremely low. At least 2 ways I can think of.

In addition the efficacy of chemical fertilizers on crop yield has been decreasing over time 29 3132. Because of these concerns there is a growing demand for. Pollutes air and water.

The problem with chemical fertilizers is that it can infiltrate the soil and can make its way to the groundwater and even surface water like rivers and lakes through runoffs which can result in contamination. The overuse of chemical fertilizers hardens the soil reduces soil fertility pollutes air water and soil and lessens important nutrients of soil and minerals thereby bringing hazards to. Pls follow for updates.

They contain essential nutrients required by the plants. Rate of nitrogen fertilizers application has a close relationship with nitrate accumulation in surrounding environment groundwater as well as leafy and root vegetables. Producing fertilizers particularly nitrogen is an energy-intensive and thus CO2 intensive process.

Excessive use of chemical fertilizers causes environmental pollution both at the manufacturing and application sites. Constant use of chemical fertilizer can alter the pH of soil increase pests acidification and soil crust which results in decreasing organic matter load humus load useful organisms stunting plant growth and even become responsible for the emission of greenhouse gases. The over-use of chemical fertilizers can lead to soil acidification because of a decrease in organic matter in the soil.

On the other hand alkaline soils with high p H content is neutralized by addition of organic matter content in the soil. Hope it is helpful. If phosphoric acid PA is added to soil the molecule will always acidify soil as H ions will be released - one H ion if the soil pH is less than 62 and two H ions is the soil pH is above 82.

Here we refer to their acidity due primarily to the excessive use of fertilizers and other chemical solutions that have the effect of lowering the pH. Ravi Karnataka Higher Education Minister. Chemical fertilizers are harmful to soil fertility in long term hence its use is not encouraged here are a few points on why shall farmers not use chemical fertilizers.

Excessive use of fertilizers by farmers and gardeners can result to the leakage of nitrogen and phosphates in soil or water. Fertilizers are the chemicals that help plants to grow. However excessive use of chemical fertilizers has led to several issues such as serious soil degradation nitrogen leaching soil compaction reduction in soil organic matter and loss of soil carbon.

One of the most common solutions for acid soils is calcium carbonate a white powder with the chemical formula CaCO 3. When the soil is alkaline the potential acidification by a fertilizer like ammonium sulphate AS very much depends on the buffering capacity of the soil. Fertilizers contain the maximum amount of mineral acids so they increase the acidity of soils and it can be neutralized by addition of calcium hydroxide or other basic chemicals.

Clay soils have an ability to buffer the effects of excess chemical fertilization. The form of P fertilizer added to soil can affect soil acidity principally through the release or gain of H ions by the phosphate molecule depending on soil pH Figure 2. Excessive use may also burn.

Farmers use fertilizers frequently to increase crop production. In conventional agriculture however chemical fertilizers are frequently used to obtain higher crop yields but only 1040 of the. It hardens the soil.

Soil in Indian farms has lost its fertility because of overuse of chemical fertilisers according to CT. When water soluble nitrogen fertilizers are applied to the soil a good portion of added nutrients does not become available to the plants but is lost to the ground water through leaching or run off. When its high in carbonates the pH.

But overuse of these fertilizers cause damage to the plants and reduces soil fertility. OVERUSING FERTILIZER CAN MAKE SOIL UNFERTILE ESPECIALLY IF ITS CHEMICAL AND CAN DECLINE THE PLANTS. Phosphate mining is also not good for the environment etc.

The unreasonable use of chemical fertilizers has negatively impacted the environment caused food security issues and reduced our dependency on the positive services that soil biodiversity provides for plant performance 123. Secondly all the excess fertilizer ends up in. Depletes essential soil nutrients and minerals.

Chemical fertiliser overuse can contribute to soil acidification and soil crust thereby reducing the content of organic matter humus content beneficial species stunting plant growth altering the pH of the soil growing pests and. Nitrogen applied to fields in large amounts over time damages topsoil resulting in reduced crop yields. Nitrogen can remain in the water for several years which can contain excessive levels of nirates and nitrites.
